They also wrote a bunch of events in-between - War of Kings, Realm of Kings, as well as the Thanos Imperative. I'm pretty sure they were also writing Guardians of the Galaxy at the time.
Saying that this had something to do with Bendis upcoming era of the Cosmic comics seems rather disingenuine to me - rather, it's quite possible that they chose to drop this storyline in order to go with the Sphinx as a villain for their last story, or maybe the event-comics where more their flair, or perhaps they plum forgot about it, since they had 10,000 other storylines going, a lá Claremont in his hey-day.
I suppose a final finger can be pointed at Marvel, since they were probably the ones pushing for so many events towards the end of their runs.
Still... Marvel gave them the Annihilators series as well... while Bendis was doing his GotG thing, yet they still didn't address this plot-thread there...
